    Abstract: Semiconductor devices having one or more vias filled with an electrically conductive material are disclosed herein. In one embodiment, a semiconductor device includes a semiconductor substrate having a first side, a plurality of circuit elements proximate to the first side, and a second side opposite the first side. A via can extend between the first and second sides, and a conductive material in the via can extend beyond the second side of the substrate to define a projecting portion of the conductive material. The semiconductor device can have a tall conductive pillar formed over the second side and surrounding the projecting portion of the conductive material, and a short conductive pad formed over the first side and electrically coupled to the conductive material in the via.

    Abstract: A semiconductor device assembly can include a first die package comprising a bottom side; a top side; and lateral sides extending between the top and bottom sides. The assembly can include an encapsulant material encapsulating the first die package. In some embodiments, the assembly includes a cooling cavity in the encapsulant material. The cooling cavity can have a first opening; a second opening; and an elongate channel extending from the first opening to the second opening. In some embodiments, the elongate channel surrounds at least two of the lateral sides of the first die package. In some embodiments, the elongate channel is configured to accommodate a cooling fluid.

    Abstract: A method of manufacturing a semiconductor device having a conductive substrate having a first surface, a second surface opposite the first surface, and a passivation material covering a portion of the first surface can include applying a seed layer of conductive material to the first surface of the conductive substrate and to the passivation material, the seed layer having a first face opposite the conductive substrate. The method can include forming a plurality of pillars comprising layers of first and second materials. The method can include etching the seed layer to undercut the seed layer between the conductive substrate and the first material of at least one of the pillars. In some embodiments, a cross-sectional area of the seed layer in contact with the passivation material between the first material and the conductive substrate is less than the cross-sectional area of the second material.

    Abstract: Systems and methods for uniform back side exposure of through-silicon vias (TSVs) are disclosed. In one embodiment, a semiconductor device comprises a substrate having a front side with circuit elements formed thereon, and a back side opposite the front side. A TSV extends between the front side and the back side of the substrate, and a dummy feature is disposed over the back side of the substrate, the dummy feature laterally spaced apart from the TSV and substantially coplanar with the TSV. In another embodiment, a semiconductor device comprises a substrate having a TSV formed therethrough, with a control material disposed over the back side of the substrate, the TSV substantially coplanar with the control material.
